This analogue reverb unit was considerably cheaper than the digital delay units at the time, and had a very unique and great sound to it. I’m not sure what happened to it.
In this case, for some odd reason, I didn’t buy another Yamaha product. It makes even less sense, as the Yamaha SPX-90, 900, 1000 multi-effects units were industry standards. Once again it came down to bangs to bucks, at least in terms of the specs on paper. I recall the sales guy at the store telling me that the Yamaha SPX-1000 “gets records made”. For some reason, that bit of rhetoric pissed me off, and I think I may have partially bought the Quadraverb out of spite.
